"You must look to South Africa where the whites and coloreds could have asked for their own state in Cape Town, and agitated for this, but instead they wanted to keep the country together. The reason for this is that any such secession would have meant giving up all parts of the country rich in gold, diamonds, and many other things. South Africa is an extreme case and secession, where a minority is five or ten percent of the population...here it might happen. But it's a net loss to have the Boers migrate out of the land their ancestors tamed and built, and it would be a net loss in America if it had to happen what some of you want, to cede the southwest to Mexico, or whatever other schemes are discussed."
